And while the result of the match between Group A rivals Kuban Krasnodar and St Gallen could seal their qualification for the last 32 ahead of kick-off, another victory for Swansea over the La Liga heavyweights would also book a spot in the knock-out stages.

And Laudrup hopes his side can overcome the ‘real’ Valencia this time, having played against 10 men for 80 minutes in the Mestalla following Adil Rami’s red card.

Laudrup said: “It is a boost to have beaten them out there but all the Spanish players here know it wasn’t the top Valencia we met. We played well, but they had a man sent off.

“I’ve seen their two (Europa) away games and they played well. That was the real Valencia with these players they have got.

“Beating them twice would make it an enormous result. Valencia are a huge club. Okay, they are passing through a difficult moment right now, but they are still a big club.

“I will go into the game with the mentality that we have to win – either to qualify or to finish top. The most important thing is to move on to the knock-out stage.”

Valencia have already qualified for the last 32, but lie in a lowly 11th spot in La Liga after just one win in their last seven domestic fixtures.

That has left coach Miroslav Djukic fighting for his job ahead of Sunday’s crunch home clash with Osasuna.

Laudrup feels Valencia have under-achieved this season:

“We are talking about a club with history, a team that has been in two consecutive finals in the Champions League and won a couple of titles with (Rafa) Benitez. They used to be third for the last six or seven years, but they are definitely not now because of Atletico (Madrid).

“The problem is they are not even fourth or fifth and are suddenly mid-table. That is very difficult for the fans and press to handle and cope with.

“But they should be higher in the league and with the players they have they could go up to four, five or six (in the table).”

Swansea welcome back former Valencia wideman Pablo Hernandez after just 29 minutes of first-team action since September 1 following a thigh injury.
